There are two sparsely-populated debris belts in the system; one, lying between Qinglong and sigma Draconis, is made up of warm asteroids, while the other, lying between the orbits of Xuanlong and Zhulong, contains icy asteroids and comets. The four outer planets are populated by a variety of Genen families, Aioids, cryoborgs, and haloist clades - these are generally Zoeific, Sophic, Keterist, or non-aligned. |
